UT343D is a high-performance composite coating thickness gauge that combines iron based (FE) and non-ferrous based (NFE) measurements. The product has the characteristics of high precision, stable and reliable performance, and non-destructive measurement. It also has functions such as single point and multi-point averaging algorithms for industrial products and fast judgment. The product is based on the principles of electromagnetic induction and eddy current measurement to detect the thickness of magnetic metal coatings and non-magnetic metal coatings, respectively. It is an essential instrument for industries such as automobile manufacturing, sales, evaluation, metal processing, painting, and inspection. It is widely used in industries and fields such as manufacturing, metal processing, aerospace, shipbuilding, high-speed trains, scientific research, quality inspection, etc
